“…To increase CaCO 3 deposition and maximize CO 2 fixation, we propose a shift, from casting and bioprinting to robotic deposition, leveraging CAD tools at the architectural scale. Doing so could optimize geometrical porosity, increase light exposure and consequently, encourage cyanobacterial deposition within the biomixture (Armaly et al, 2023a). Optimizing geometrical properties for enhancing performance is at the core of architectural CAD techniques and is linked to manufacturing through customized computer-aided manufacturing workflows (Armaly et al, 2023a).…”

Optimizing geometrical properties for enhancing performance is at the core of architectural CAD techniques and is linked to manufacturing through customized computer-aided manufacturing workflows (Armaly et al, 2023a). In this study, the unique interrelations between biological activities, geometrical properties and robotic AM techniques were leveraged, to generate connections between the biological and architectural scales, while outlining tradeoffs that need to be addressed throughout the three phases of the co-fabrication workflow.…”

“…For example, the geometrical design (i.e., geometrical porosity and increased surface area) could be informed by environmental conditions, such as increased light exposure, which is necessary for cyanobacterial viability and could enhance biological activity (Clark et al, 2018). Similar tradeoffs regarding geometrical properties and cell behavior include the design of the printing tool path, one that considers cyanobacterial mobility, for example, since sharp angles could reduce uniform integration of the cells with the material (Arellano-Caicedo et al, 2021;Armaly et al, 2023a). When fabricating with photosynthetic bacteria, such tradeoffs within AM processes could govern the bacterial viability and in turn, the biological deposition and solidification outcome.…”

“…Such fabrication setups could enable the production of relatively large-scale architectural modular components, such as blocks and panels. We are currently working on the design of architectural components, subject to the size constraints of the incubator (40 × 40 × 40 cm) (Armaly et al, 2023a). When addressing 3D concrete and earth printing within architectural production, tool path designs impact the components' fabrication process and their structural performance (Breseghello et al, 2021;Gomaa et al, 2021).…”

“…Today, using AM workflows, designers are able to interact with new materials, customize printing tool paths for complex material distribution, and enhance the performance of manufactured designs (Mehrpouya et al, 2021;Cohen and Barath, 2023). Moreover, computer-aided design (CAD) techniques for 3D printing enable the optimization of structural performance and material use (Breseghello et al, 2021;Armaly et al, 2023a). In the field of biology, AM in the form of bioprinting has been introduced, to enable high-resolution printing of living materials in spatially defined structures (Balasubramanian et al, 2021).…”

With the increasing need for architectural sustainability, biodesign offers a new approach to incorporating living organisms in building materials. Bacteria hold a range of biological activities that impact their environment, and which could enable the solidification of inorganic materials; this has already been seen with microbially-induced carbonate precipitation that strengthens bonds between sand particles. This paper describes the novel development of an additive co-fabrication manufacturing process, demonstrating an interdisciplinary approach of architecture and microbiology. Specifically, the activity of a biological deposition (i.e., cyanobacterial calcium carbonate precipitation) and its integration with that of a robotic deposition (i.e., a sand-based biomixture) within an architectural biofabrication workflow. Two bacterial strains were successfully grown in potential sand-based construction materials. Microbiological protocols, such as optical density and fluorescence measurements, were then applied to identify parameters, for harvesting light through photosynthesis and harnessing it to the sedimentation of calcium carbonate. Assessments of the proposed mechanical delivery system and printing properties enabled the outlining of a suitable robotic deposition system for sand-based mixtures. Through examinations of these microbiological and mechanical protocols, this paper outlines design strategies and trade-offs for an integrated workflow, that corresponds with both the biological (micro) and architectural (macro) scales.
